The transmitters 22a and 22b transmit optical signals to other transmission devices. The receiver RX receives an optical signal transmitted from another transmission device.
　図１に示すように、可視化装置ＱＡは、信号変化検出部１と、接続データベース２と、表示制御部３を備えている。信号変化検出部１は、２つの受信部ＲＸに接続されている。 As shown in FIG. 1, the visualization device QA includes a signal change detection unit 1, a connection database 2, and a display control unit 3. The signal change detector 1 is connected to two receivers RX.
　図２に示すように、伝送装置ＴＲ-１に搭載される可視化装置ＱＡ１は、２つの受信部ＲＸ-１-２、ＲＸ-１-３に接続されている。伝送装置ＴＲ-２に搭載される可視化装置ＱＡ２は、２つの受信部ＲＸ-２-１、ＲＸ-２-３に接続されている。伝送装置ＴＲ-３に搭載される可視化装置ＱＡ３は、２つの受信部ＲＸ-３-１、ＲＸ-３-２に接続されている。 As shown in FIG. 2, the visualization device QA1 mounted on the transmission device TR-1 is connected to two receiving units RX-1-2 and RX-1-3. A visualization device QA2 mounted on the transmission device TR-2 is connected to two receivers RX-2-1 and RX-2-3. A visualization device QA3 mounted on the transmission device TR-3 is connected to two receivers RX-3-1 and RX-3-2.
　伝送装置ＴＲ-１とＴＲ-２は、２本の光ファイバＦＢ-１-２、ＦＢ-２-１により接続されている。即ち、伝送装置ＴＲ-１の送信部２２ｂから送信される光信号は、光ファイバＦＢ-１-２を経由して受信部ＲＸ-２-１に受信され、伝送装置ＴＲ-２の送信部２２ａから送信される光信号は、光ファイバＦＢ-２-１を経由して受信部ＲＸ-１-２に受信される。 The transmission devices TR-1 and TR-2 are connected by two optical fibers FB-1-2 and FB-2-1. That is, the optical signal transmitted from the transmission unit 22b of the transmission device TR-1 is received by the reception unit RX-2-1 via the optical fiber FB-1-2 and transmitted to the transmission unit 22a of the transmission device TR-2. The optical signal transmitted from is received by the receiver RX-1-2 via the optical fiber FB-2-1.
　伝送装置ＴＲ-２とＴＲ-３は、２本の光ファイバＦＢ-２-３、ＦＢ-３-２により接続されている。即ち、伝送装置ＴＲ-２の送信部２２ｂから送信される光信号は、光ファイバＦＢ-２-３を経由して受信部ＲＸ-３-２に受信され、伝送装置ＴＲ-３の送信部２２ａから送信される光信号は、光ファイバＦＢ-３-２を経由して受信部ＲＸ-２-３に受信される。 The transmission devices TR-2 and TR-3 are connected by two optical fibers FB-2-3 and FB-3-2. That is, the optical signal transmitted from the transmission unit 22b of the transmission device TR-2 is received by the reception unit RX-3-2 via the optical fiber FB-2-3 and transmitted to the transmission unit 22a of the transmission device TR-3. The optical signal transmitted from is received by the receiver RX-2-3 via the optical fiber FB-3-2.
　伝送装置ＴＲ-３とＴＲ-１は、２本の光ファイバＦＢ-３-１、ＦＢ-１-３により接続されている。即ち、伝送装置ＴＲ-３の送信部２２ｂから送信される光信号は、光ファイバＦＢ-３-１を経由して受信部ＲＸ-１-３に受信され、伝送装置ＴＲ-１の送信部２２ａから送信される光信号は、光ファイバＦＢ-１-３を経由して受信部ＲＸ-３-１に受信される。 The transmission devices TR-3 and TR-1 are connected by two optical fibers FB-3-1 and FB-1-3. That is, the optical signal transmitted from the transmission unit 22b of the transmission device TR-3 is received by the reception unit RX-1-3 via the optical fiber FB-3-1 and transmitted to the transmission unit 22a of the transmission device TR-1. The optical signal transmitted from is received by the receiver RX-3-1 via the optical fiber FB-1-3.
　以下では、各可視化装置、各伝送装置、各受信部、各光ファイバを特定して示す場合には、「可視化装置ＱＡ１」、「伝送装置ＴＲ-１」、「受信部ＲＸ-１-２」、「光ファイバＦＢ-２-１」のようにサフィックスを付して示す。各可視化装置、各伝送装置、各受信部、各光ファイバを特定しない場合及び総称して示す場合には、「可視化装置ＱＡ」、「伝送装置ＴＲ」、「受信部ＲＸ」、「光ファイバＦＢ」のようにサフィックスを付さずに示すことにする。 In the following, when each visualization device, each transmission device, each reception unit, and each optical fiber are specified, they are referred to as “visualization device QA1,” “transmission device TR-1,” and “reception unit RX-1-2.” , with suffixes such as "optical fiber FB-2-1". When each visualization device, each transmission device, each reception unit, and each optical fiber are not specified or collectively indicated, “visualization device QA”, “transmission device TR”, “reception unit RX”, “optical fiber FB ” without a suffix.
　図１に示すように、受信部ＲＸは、光ファイバＦＢに接続されており、光ファイバＦＢを経由して送信される光信号を受信する。例えば、図２に示す受信部ＲＸ-１-２は、伝送装置ＴＲ-２の送信部２２ａから送信される光信号を受信する。 As shown in FIG. 1, the receiver RX is connected to the optical fiber FB and receives an optical signal transmitted via the optical fiber FB. For example, the receiver RX-1-2 shown in FIG. 2 receives an optical signal transmitted from the transmitter 22a of the transmission device TR-2.
　受信部ＲＸは、受信した光信号の特徴量を信号変化検出部１に出力する。なお、１つの伝送装置ＴＲに搭載される受信部ＲＸの数は２つに限定されない。 The receiver RX outputs the feature quantity of the received optical signal to the signal change detector 1 . Note that the number of receivers RX mounted in one transmission device TR is not limited to two.
　光信号の特徴量は、例えば光信号の受光レベル、多値変調のコンスタレーションの分散、誤り訂正前ビットエラーレートなどである。これらの特徴量の情報は、ＤＭＭ（Digital Diagnostic Monitoring）、ＴＡＩ（Transponder Abstraction Interface）を通して取得することができる。 The feature quantities of the optical signal are, for example, the received light level of the optical signal, the dispersion of the multi-level modulation constellation, the bit error rate before error correction, and the like. Information on these feature amounts can be obtained through DMM (Digital Diagnostic Monitoring) and TAI (Transponder Abstraction Interface).
　信号変化検出部１は、受信部ＲＸから出力される特徴量を解析し、特徴量の変化を検出する。例えば、光ファイバＦＢに曲げ応力などのピンチ操作が加えられた場合には、光ファイバＦＢにて送信される光信号に、受光レベルの低下、コンスタレーションの分散の増大、誤り訂正前ビットエラーレートの上昇などの、各特徴量に変化が生じる。なお、「ピンチ操作」とは、例えば人間の指で光ファイバＦＢをつまんで湾曲させる操作を指す。ピンチ操作は、物理的な刺激の一例である。 The signal change detection unit 1 analyzes the feature quantity output from the reception unit RX and detects changes in the feature quantity. For example, when a pinching operation such as bending stress is applied to the optical fiber FB, the optical signal transmitted through the optical fiber FB will experience a decrease in the received light level, an increase in the dispersion of the constellation, and a bit error rate before error correction. A change occurs in each feature value, such as an increase in The “pinch operation” refers to an operation of pinching and bending the optical fiber FB with human fingers, for example. A pinch operation is an example of a physical stimulus.
　信号変化検出部１は、受信部ＲＸから出力される特徴量に変化が生じた場合に、対象となる光ファイバＦＢに曲げ応力などのピンチ操作が加えられたことを検出する。 The signal change detection unit 1 detects that a pinch operation such as bending stress is applied to the target optical fiber FB when a change occurs in the feature quantity output from the reception unit RX.
　ここで、誤り訂正後ビットエラーレートがエラーフリーであれば、光ファイバＦＢに適度な曲げ応力などのピンチ操作を加えたとしても、この光ファイバＦＢによる通信に対する影響は発生しない。即ち、光ファイバＦＢに適度なピンチ操作を加えることにより、光ファイバＦＢによる通信に影響を与えることなく、上記した特徴量を意図的に変化させることができる。 Here, if the bit error rate after error correction is error-free, even if a pinching operation such as an appropriate bending stress is applied to the optical fiber FB, there will be no effect on communication by this optical fiber FB. In other words, by applying an appropriate pinching operation to the optical fiber FB, it is possible to intentionally change the feature amount without affecting the communication through the optical fiber FB.
　信号変化検出部１は、受信部ＲＸで受信された光信号にて、特徴量の変化を検出した場合は、この受信部ＲＸのＩＤを表示制御部３に出力する。 The signal change detection unit 1 outputs the ID of the reception unit RX to the display control unit 3 when detecting a change in the feature quantity in the optical signal received by the reception unit RX.
　接続データベース２は、受信部ＲＸにおける各種の接続に関する情報を示す接続関係テーブルを記憶する。図３は、接続データベース２に記憶されている接続関係テーブルの例を示す説明図である。図３に示すように、接続関係テーブルには、各受信部ＲＸのＩＤ、受信部ＲＸが搭載されている伝送装置ＴＲ（搭載伝送装置）のＩＤ、受信部ＲＸとの間で通信を行う伝送装置ＴＲ（対向伝送装置）のＩＤ、伝送装置ＴＲの管理用ＩＰアドレス、及び設置場所の対応を示す情報が記述されている。 The connection database 2 stores a connection relationship table showing information on various connections in the receiving unit RX. FIG. 3 is an explanatory diagram showing an example of the connection relationship table stored in the connection database 2. As shown in FIG. As shown in FIG. 3, the connection relationship table contains the ID of each receiver RX, the ID of the transmission device TR (transmission device) in which the receiver RX is mounted, and the transmission data for communicating with the receiver RX. Information indicating the correspondence between the ID of the device TR (opposite transmission device), the management IP address of the transmission device TR, and the installation location is described.
　例えば図３に示すように、受信部ＲＸ-１-２（ＩＤが「ＲＸ-１-２」の受信部）は、伝送装置ＴＲ-１（ＩＤが「ＴＲ-１」の伝送装置）に搭載されており、伝送装置ＴＲ-２（ＩＤが「ＴＲ-２」の伝送装置）と対向している。また、受信部ＲＸ-１-２の管理用ＩＰアドレスは「１９２．１６８．１．１」であり、設置場所は、「Ｖｅｎｕｅ-１」である。 For example, as shown in FIG. 3, the receiver RX-1-2 (the receiver with the ID "RX-1-2") is installed in the transmitter TR-1 (the transmitter with the ID "TR-1"). and faces the transmission device TR-2 (the transmission device whose ID is "TR-2"). The management IP address of the receiving unit RX-1-2 is "192.168.1.1" and the installation location is "Venue-1".
　図１に戻って、表示制御部３は、画像表示用のディスプレイ３１を備えている。表示制御部３は、信号変化検出部１から出力された受信部ＲＸのＩＤを取得する。例えば、受信部ＲＸ-１-３である場合には、この受信部ＲＸ-１-２に対応する各種の情報を、接続データベース２に記憶されている接続関係テーブルから取得する。表示制御部３は、取得した各種の情報に基づいて、物理的な刺激を加えた光ファイバＦＢを特定し、特定した光ファイバＦＢを示す画像（識別情報）をディスプレイ３１に表示する。即ち、表示制御部３は、光信号に変化が生じた光ファイバＦＢを示す識別情報を表示する。ディスプレイ３１として、液晶ディスプレイ、透過型ヘッドマウントディスプレイなどを用いることができる。 Returning to FIG. 1, the display control unit 3 includes a display 31 for image display. The display controller 3 acquires the ID of the receiver RX output from the signal change detector 1 . For example, in the case of the receiving unit RX-1-3, various information corresponding to this receiving unit RX-1-2 is obtained from the connection relationship table stored in the connection database 2. FIG. The display control unit 3 identifies the optical fiber FB to which the physical stimulus is applied based on the acquired various information, and displays an image (identification information) indicating the identified optical fiber FB on the display 31 . That is, the display control unit 3 displays identification information indicating the optical fiber FB in which the optical signal has changed. As the display 31, a liquid crystal display, a transmissive head-mounted display, or the like can be used.
　［第１実施形態の動作］
　次に、図４に示すフローチャートを参照して、第１実施形態に係る可視化装置ＱＡの動作について説明する。 [Operation of the first embodiment]
Next, the operation of the visualization device QA according to the first embodiment will be described with reference to the flowchart shown in FIG.
　ユーザは、複数の光ファイバＦＢのうちの所望の光ファイバＦＢが、どの伝送装置ＴＲに接続されているものかを調べたい場合に、所望の光ファイバＦＢに曲げ応力などのピンチ操作を加える。その結果、所望の光ファイバＦＢに接続されている受信部ＲＸで受信される光信号の特徴量に変化が発生する。ステップＳ１１において、信号変化検出部１は、受信部ＲＸで受信される光信号に含まれる特徴量の変化を検出する。 When the user wants to find out to which transmission device TR the desired optical fiber FB among the plurality of optical fibers FB is connected, the user applies a pinching operation such as bending stress to the desired optical fiber FB. As a result, a change occurs in the feature quantity of the optical signal received by the receiver RX connected to the desired optical fiber FB. In step S11, the signal change detector 1 detects a change in the feature quantity included in the optical signal received by the receiver RX.
　ステップＳ１２において、信号変化検出部１は、各受信部ＲＸで検出される光信号の特徴量に変化が発生したか否かを判定する。特徴量の変化が発生した場合には（Ｓ１２；ＹＥＳ）、ステップＳ１３に処理を進め、そうでなければ（Ｓ１２；ＮＯ）、ステップＳ１１に処理を戻す。 In step S12, the signal change detector 1 determines whether or not there is a change in the feature amount of the optical signal detected by each receiver RX. If the feature amount has changed (S12; YES), the process proceeds to step S13; otherwise (S12; NO), the process returns to step S11.
　ステップＳ１３において、信号変化検出部１は、特徴量の変化が発生した受信部ＲＸを特定し、特定した受信部ＲＸのＩＤを表示制御部３に出力する。 In step S<b>13 , the signal change detection unit 1 identifies the reception unit RX in which the change in feature amount has occurred, and outputs the ID of the identified reception unit RX to the display control unit 3 .
　ステップＳ１４において、表示制御部３は、接続データベース２に記憶されている接続関係テーブルを参照し、特定した受信部ＲＸが搭載される搭載伝送装置のＩＤ、及び対向伝送装置のＩＤを取得し、双方を接続する光ファイバＦＢを特定する。例えば、図３に示すように、受信部ＲＸのＩＤが「ＲＸ-１-２」である場合には、搭載伝送装置のＩＤが「ＴＲ-１」、対向伝送装置のＩＤが「ＴＲ-２」であり、これらを接続する光ファイバＦＢは、ＦＢ-２-１であることが特定される。 In step S14, the display control unit 3 refers to the connection relation table stored in the connection database 2, acquires the ID of the mounted transmission device in which the specified receiving unit RX is mounted, and the ID of the opposite transmission device, Identify the optical fiber FB that connects the two. For example, as shown in FIG. 3, when the ID of the receiver RX is "RX-1-2", the ID of the installed transmission device is "TR-1" and the ID of the opposite transmission device is "TR-2". , and the optical fiber FB connecting them is identified as FB-2-1.
　ステップＳ１５において、表示制御部３は、特定した光ファイバＦＢの情報を含む可視化画像を、ディスプレイ３１に表示する。図５は、ディスプレイ３１に表示する可視化画像Ｄ１の例を示す説明図である。図５に示すように、可視化画像Ｄ１には、各伝送装置ＴＲ-１、ＴＲ-２、ＴＲ-３と、各伝送装置間を接続する光ファイバＦＢを示す矢印が表示されている。また、特定された光ファイバＦＢ-１-２が強調表示されている。具体的には、光ファイバＦＢ-１-２は、他の光ファイバＦＢよりも太線で表示される。即ち、ユーザがピンチ操作を加えた光ファイバＦＢ-１-２が太線で表示されることにより可視化される。その結果、ユーザは、所望の光ファイバＦＢがどの伝送装置ＴＲに接続されているかを容易に認識できる。 In step S15, the display control unit 3 displays on the display 31 a visualized image including information on the specified optical fiber FB. FIG. 5 is an explanatory diagram showing an example of the visualized image D1 displayed on the display 31. As shown in FIG. As shown in FIG. 5, the visualized image D1 displays arrows indicating transmission devices TR-1, TR-2, and TR-3 and optical fibers FB connecting the transmission devices. Also, the specified optical fiber FB-1-2 is highlighted. Specifically, the optical fiber FB-1-2 is displayed with a thicker line than the other optical fibers FB. That is, the optical fiber FB-1-2 pinched by the user is visualized by being displayed with a thick line. As a result, the user can easily recognize to which transmission device TR the desired optical fiber FB is connected.
　［第１実施形態の効果］
　このように、第１実施形態に係る可視化装置ＱＡは、複数の光ファイバＦＢから、特定の光ファイバを可視化する可視化装置であって、各光ファイバＦＢに物理的な刺激が加えられた際の、光信号に生じる変化を検出する信号変化検出部１と、光信号に変化が生じた光ファイバＦＢを示す識別情報を表示する表示制御部３と、を備える。 [Effect of the first embodiment]
As described above, the visualization device QA according to the first embodiment is a visualization device that visualizes a specific optical fiber from a plurality of optical fibers FB. , a signal change detection unit 1 for detecting a change occurring in an optical signal, and a display control unit 3 for displaying identification information indicating an optical fiber FB in which a change has occurred in the optical signal.
　第１実施形態では、ユーザにより曲げ応力などのピンチ操作が加えられた光ファイバＦＢがディスプレイ３１に表示される可視化画像Ｄ１上で太線等により強調表示される。 In the first embodiment, the optical fiber FB to which the pinching operation such as bending stress is applied by the user is highlighted by a thick line or the like on the visualized image D1 displayed on the display 31 .
　このためユーザは、光ファイバＦＢに曲げ応力などのピンチ操作を加えるという簡単な操作で、この光ファイバＦＢがどの伝送装置ＴＲに接続されているかを視覚的に認識することができる。その結果、簡易な操作で多数の光ファイバから個々の光ファイバを識別することが可能になる。 Therefore, the user can visually recognize to which transmission device TR this optical fiber FB is connected by a simple operation of applying a pinch operation such as bending stress to the optical fiber FB. As a result, it becomes possible to identify individual optical fibers from a large number of optical fibers with a simple operation.
　即ち、本実施形態に係る可視化装置ＱＡでは、光ファイバＦＢにマーカを付加することなく、光ファイバＦＢの識別が可能になる。光ファイバＦＢにマーカを付加する場合には、付加したマーカの位置を見つける必要があるが、本実施形態では、光ファイバＦＢのどの位置からでも、該光ファイバＦＢを識別することが可能になる。 That is, with the visualization device QA according to this embodiment, it is possible to identify the optical fiber FB without adding a marker to the optical fiber FB. When adding a marker to the optical fiber FB, it is necessary to find the position of the added marker, but in this embodiment, it is possible to identify the optical fiber FB from any position on the optical fiber FB. .
　［第２実施形態の構成］
　次に、第２実施形態について説明する。図６は、第２実施形態に係る可視化装置ＱＢ、及びその周辺機器の構成を示すブロック図である。図６に示す可視化装置ＱＢは、前述した図１に記載した可視化装置ＱＡと対比して、ピンチ検出部５（刺激検出部）、及び判定部６を備えている点で相違する。ピンチ検出部５は、カメラ（撮像部）に接続されている。それ以外の構成要素については、前述した図１と同様であるので、同一符号を付して構成説明を省略する。 [Configuration of Second Embodiment]

　カメラ４は、例えば光ファイバＦＢの近傍に設けられている。カメラ４は、各光ファイバＦＢに物理的な刺激が加えられる様子を撮像する。カメラ４は、撮像した画像をピンチ検出部５に出力する。 The camera 4 is provided near the optical fiber FB, for example. A camera 4 captures an image of a physical stimulus being applied to each optical fiber FB. The camera 4 outputs the captured image to the pinch detection section 5 .
　ピンチ検出部５は、カメラ４で撮像された画像から、光ファイバＦＢにピンチ操作などの物理的な刺激が加えられたことを検出する。カメラ４は、例えば透過型ヘッドマウントディスプレイに搭載することができる。 The pinch detection unit 5 detects from the image captured by the camera 4 that a physical stimulus such as a pinch operation is applied to the optical fiber FB. The camera 4 can be mounted on, for example, a transmissive head-mounted display.

Next, the operation of the visualization device QB according to the second embodiment will be described with reference to the flowchart shown in FIG.
　ステップＳ３１において、信号変化検出部１は、受信部ＲＸで受信される光信号に含まれる特徴量の変化を検出する。 In step S31, the signal change detector 1 detects a change in the feature quantity included in the optical signal received by the receiver RX.
　ステップＳ３２において、信号変化検出部１は、各受信部ＲＸで検出される光信号の特徴量に変化が発生したか否かを判定する。特徴量の変化が発生した場合には（Ｓ３２；ＹＥＳ）、ステップＳ３３に処理を進め、そうでなければ（Ｓ３２；ＮＯ）、ステップＳ３１に処理を戻す。 In step S32, the signal change detector 1 determines whether or not there is a change in the feature amount of the optical signal detected by each receiver RX.
